machines, CPC versions were usually ported versions of the Spectrum games, with the graphics display on the more-capable CPC reconfigured to be close to that of the more primitive Spectrum. Z80 development was primarily run by Damian Scattergood. The team developed a graphics display system for the CPC 464 that emulated the Spectrum screen layout which meant graphics routines could be ported quickly. Damian also developed his own macro programming language that meant that code could be compiled and shared instantly across both platforms. Z80 development was actually done on a PC where the code could be edited and compiled quickly, and then was ported via RS232 direct onto the Spectrum and CPC machines for testing. List of games The company produced a number of games during its brief existence, to somewhat mixed reviews. These were largely ports of existing arcade games (Vigilante for example) or original movie tie-ins (The Running Man) but there were also some original game concepts (e.g. Phantom Fighter): The Deep (1988) If It Moves, Shoot It! (1988) Phantom Fighter (1988) The Running Man (1989) Vigilante (1989) Michael Jackson's Moonwalker (1989) Fallen Angel (1989) Treasure Trap (1990) The Running Man The intro sequence for the Amiga version of 'The Running Man' occupied practically one full 800k diskette of the two diskette set. Running in a continuous loop till interrupted, it featured digitised voice, music and video sequences from the film, and so was often left running in computer stores as an Amiga feature demonstrator.
